/* Integer object interface */ | |
/* | |
PyIntObject represents a (long) integer. This is an immutable object; | |
an integer cannot change its value after creation. | |
There are functions to create new integer objects, to test an object | |
for integer-ness, and to get the integer value. The latter functions | |
returns -1 and sets errno to EBADF if the object is not an PyIntObject. | |
None of the functions should be applied to nil objects. | |
The type PyIntObject is (unfortunately) exposed here so we can declare | |
_Py_TrueStruct and _Py_ZeroStruct in boolobject.h; don't use this. | |
